Application filed September 26, 1921. Serial No. 503,437.

To all whom it may concern:

Be it known that l, FRANCIS luvmcsronn 33am subject of the Wing of 3 inresiding at No, 109 forest Road, ham England, have invented linprov inand Relating to Apparatus tor l. Yarn the like, of which the rollon is aspecification.

This invention has reference to improve ments in and relating toapparatus for wind in}; yarn and the like and has particular referenceto the type wherein the thread control mechanism or thread guides arecan ried by a rod or traverse bar adapted to reciprocated from a camshaft.

The object of the present invention is the provision of means forproducing a balanced efiort on the main or cam she-it, means fordecreasing the wear of the, gearing actuating said shaft, means forequalizin the resistance to rotation of said shaft during the whole ofeach revolution, and improvements in the means for and in the methodactuating the winding mechanism.

The principal feature of this invention consists in dividing thetraverse bar into independent lengths and actuatin such lengths by setsof cams placed out or phase with one another on the cam shaft.

ltn order that this invention may be more fully understood referencewill now be made to the accompanying drawing, wherein Fig. l is a partfront elevation ot a winding machine constructed according to thepresent invention,

Fig. 2 is an end view thereof,

Fig. 3 is a view showing the relative (llS position of the cams, and

Fig. i is a detail view of one type of rock ing lever.

The machine as shown herewith comprises a frame 1., carrying independentspindles 2 upon which the yarn 3 to be wound is mounted. Such yarnpasses through suitable trusioning mechanism to the control lllt anism 5carried by control rods 6, and i 1= thence to the bobbins 7 mounted uponindependent rotating spindles 8.

Also each rod 6 carries complete control mechanism 5 of any usual andconvenient type. t

Rotary motion is imparted to the driving shaft 9 "from any convenientsource there being provided fast and loose pulleys l0 and 11respectively and a fork 12 if and when a belt drive is employed. Fulicys13 on the shaft 9 rotary motion to the spindles 8 through the medium ofpulleys 14- mounted upon such spindles and belts or bands 15. A pulley16 on the shaft 9 imparts rotary motion to a pulley 17 carried by acountershait 18 by means of a belt 19 and said countershaft carries atoothed pinion 20 in mesh with a toothed wheel 21 on a secondcountershait 22. Coaxial with the wheel 21 is a pinion 23 engaging atoothed wheel 24 mounted upon the cam shaft 25, such shaft extendinglongitudinally the length of the machine. Further in conjunction withthe thread tensioning mechanism the cam shaft imparts rotary motion to aroller 26 by means of a belt and pulleys as indicated at 27.

The various elements as above described are constructed and arranged inaccordance with present practice and no claim is made thereto and thisinvention is not limited to the application to a'machine provided withsuch elements excepting as aforesaid.

According to present practice all of the rods 6 are carried by one andthe same traverse bar, reoiprocatory motion being imparted thereto fromone or more cams mounted in phase upon the cam shaft 25.

in the carrying into efiect of the present invention the traverse bar isdivided into independent lengths and for the purpose of description thebar as shown herewith is divided into three lengths 28, 28 and 28 but itwill be understood that the bar may be otherwise conveniently divided.Each length 28 28 and 28 carries a certain proportion of the controlrods 6 and such lengths are independently actuated by guided rciprocating members or traverse bar actuating rods 6 from sets of cams29, 29 and 29 mounted upon the cam shaft 25, there being the, samenumber of sets of cams as there are lengths of traverse bar.

For the production of a balanced effort, which is the main object ofthis invention,

the sets of cams 29, 29 and 29 are placed out of phase with one anotheralthough the cams within each set are in phase. The

action of certain sets of the cams is thus opposed to the action of theother sets and while certain of the cams and lengths of traverse baractuated thereby are rising the other sets of cams and correspondinglengths oi traverse bar are falling.

in one arrangement which is illustrated herewith the cams are sodesigned that the fall thereof is twice as steep as the rise.

Consequently if three sets of cams are employed and the traverse bardivided into three equal lengths, each length being actuated by one setand such sets arranged out of phase so that whil one set is falling theother two sets are rising, then the torque produced on the cam shaft bythe first set will be opposed and equal to the torque produced on saidshaft by the second set. The resistance to rotation of the cam shaftwill then approach equality throughout the whole of each revolution.

Wh'atever design of cam is employed the above object may be readilyattained by suitably modifying the angle of phase difference between thesets of cams and the number oii lengths into which the traverse bar isdivided, the aforementioned design being submitted merely as an example.

Also in each set of cams there may be any convenient number of camsdepending upon the individual requirements of each machine.

Levers 30 pivoted to the standard at 31 carry rollers 32 hearing on therespective cams 29, there being one lever 30 to each cam, and at theirextremity remote from the pivot such levers carry rollers 33 bearing onthe lower extremities of the rods 6 means being preferably provided asindicated for varying the'etfective lengths of such rods. Fig. 3illustrates the relative disposition of the-pairs of cams 29 29 and 29with respect to one another, the position of the cams as shown-in thisfigure corresponding to the position of the bars 28", 28, 28 shown inFig. 1.

The levers 30 are preferably of the type illustrated in Fig. a, which asshown comprises parallel and similar side members 30 and 30 tween whichare accommodated the rollers 32 and 33, positioned upon shanked screwbearings 35 by nuts 36. Said type of lever is readily interchangeableand renewed and the strain produced in the retaining members thereof isbalanced particularly as opposed to the type at present used whereinonly one side member is employed.

As will be readily understood by reason of actuating a winding engine inthe improved manner as herein described the re sistanceto rotation ofthe cam shaft during the whole of each revolution is practicallyconstant, a balanced efi'ort is obtained, the running of the machine issweeter and more even, and less power is required whilst the wear on thegear is materially reduced.
